root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...

Nineteen patients with roof impingement of an anterior cruciate ligament graft had their grafts inspected during second-look arthroscopy. The diagnosis of roof impingement was suspected from the clinical findings of an effusion, extension deficit, recurrent instability, or anterior knee pain. The diagnosis was confirmed when a portion of the tibial tunnel was anterior to the tibial intersection...

Background: The risk of a second anterior cruciate ligament (ACL) injury when participating in pivoting sports after ACL reconstruction is high. Risk factors associated with are complex. Purpose: To investigate the combinations various clinical female soccer players primary unilateral reconstruction, using Classification and Regression Tree (CART) analysis. Study Design: Cohort study; Level evi...

PURPOSE To evaluate torque and the hamstring/quadriceps ratio of the knee of athletes with and without anterior cruciate ligament laxity. METHODS Twenty-eight male athletes, 19 without anterior cruciate ligament laxity and 9 with anterior cruciate ligament laxity, were evaluated with an isokinetic machine model Cybex 770. The peak torque of quadriceps and hamstrings was compared, and the hams...

BACKGROUND There is a lack of consensus regarding the magnitude of load for performing the anterior drawer test in evaluating acute ankle injuries. PURPOSE To determine how much load should be applied during the anterior drawer test to detect the integrity of the anterior talofibular ligament. METHODS First, the anterior-posterior load-displacement response of nine cadaveric ankles was meas...

{ This paper explores new techniques to improve the performance of production or rule-based systems. In particular, a rule-splitting mechanism using constraint domain analysis and a check-rule mechanism are proposed to extract internal paral-lelism among rules. This rule-splitting mechanism can also be used to solve the load balancing problem caused by culprit rules which require comparisons wi...

AIM The petrosphenoidal ligament (PSL, or Gruber's ligament) is located between the petrous apex (PA) and posterior clinoid process (PCP). Details of its anatomy are conflicting in the few studies that exist in the literature. We performed this study to describe in detail the microanatomical characteristics of Gruber's ligament. MATERIAL AND METHODS 20 human cadaveric heads (40 specimens) wer...

Proof. We check that the flow S routing all supply through the first edge is both optimal and Nash. Since S sends no supply through the second edge, S is optimal if the marginal cost of the first edge is at most that of the second: a ≤ (i+ 1)−1 a(i+ 1) ≤ 1 [ a(i+ 1)x ] (1) ≤ 1 d dx ( xax ) (1) ≤ d dx (x) (0) c1(1) ≤ c2(0), as required. Thus S is optimal. To check S is Nash, we check that the la...
